THERE ARE HUNDREDS OF GOLDFISH SPECIES AVAILABLE TODAY. MOST ORIGINATE FROM THE COMMON FEEDER TYPE. CENTURIES OF SELECTIVE BREEDING HAVE DEVELOPED SOME UNUSUAL FISH. GOLDFISH AQUARIUMS SHOULD HAVE A STRONG FILTER, AERATION, AND SPECIFIC WATER PARAMETERS. A SPECIFIC DIET IS RECOMMENDED. USUALLY NEGLECT, CROWDING AND OVERFEEDING ARE FATAL. GOLDFISH ARE GENERALLY PEACEFUL TOWARDS EACHOTHER. THEY ARE VERY COLORFUL AND SLOW MOVING FISH THAT WILL EVENTUALLY TAKE ON THEIR OWN PERSONALITY.
